1. Safety Precautions
1-1. Safety Precautions for Repairs
1) Since the equipment uses laser diode, ensure that eyes and parts of the body do not come near the laser diode while performing repair service. 2) Do not disassemble pickup to repair. If the laser diode is faulty, then replace the complete pickup assembly. 3) Perform repair services away from electrical equipments such as TV to avoid interference from these equipments. 4) Ensure to unplug the power cord from the unit before replacing any parts. 5) Ensure to insert the disc properly into the unit before use. 6) Since this equipment cannot be used as a standalone unit, it must be installed in a PC (586 or higher) with appropriate device driver from the floppy disk to verify proper operation. 7) This equipment has many parts with properties related to safety. These parts are specifically noted in the parts list and schematic drawings. Ensure to replace these parts with new parts that have the same specifications. - Since the laser diode in the optical pickup bundle can be easily damaged by the static electricity in human body or clothing, use the following grounding guidelines when handling the bundle. Wear a wrist strap with one end properly grounded. The wrist strap discharges the static electricity in human body. Work on a conductive material such as copper plate that is properly grounded. Since the static electricity stored in clothing is not easily discharged, ensure that clothing does not make a contact with the pickup bundle.
1-2. Safety Precautions for Installations
A certain semiconductor components are highly susceptible to damages caused by electrostatic discharge (ESD). Semiconductors components such integrated circuits, field effect transistors, and other semiconductor devices are examples of devices that are highly sensitive to ESD. Use the following guidelines to reduce the damages caused by the ESD. 1) Before handling any semiconductor components or parts that contains semiconductors, immediately discharge all static electricity in the body by making a contact with a grounded metallic object. A commercially available wrist strap may also be used. The static electricity must be discharged to avoid potential impact on the voltage during testing. 2) After removing ESD-sensitive components or parts, place the items on a conductive surface such as on a piece of aluminium to prevent accumulation of charges and exposure to ESD. 3) Use properly grounded soldering iron to solder or to de-solder ESD-sensitive components. 4) Only use anti-static soldering iron to de-solder ESD-sensitive components. Use of soldering irons not classified as "anti -static" has enough electrostatic charges to cause damages to the components. 5) Do not use chemical sprays such as Freon. These chemicals have enough electrostatic charges to cause damages to the ESD-sensitive components. 6) Do not remove replacement parts from the anti-static packaging until they are ready for installation. [Most of the replacement parts are packaged in conductive foam, aluminium, or other conductive materials with all the leads shorted together.] 7) Before removing the anti-static packing materials for the new parts, make a contact with the chassis or protective material for the circuits to discharge the static charges. Caution: Ensure that the power does not get transferred to the chassis or to the circuitry, and that all general safety guidelines are followed. 8) Minimize body movement when handling unprotected ESD-sensitive parts and components. (The movement of body causes build up of electrostatic charges from friction between layers of clothing, and between the shoes and the carpet which may cause damage to the components.)

This may be unsafe and may damage the product. 7) Do not use the product near water such as bathtubs, washbasins, washing machines, swimming pools, or lakes. 8) Never place the product on the bed, sofa, radiator, or near any heat source. 9) Power: Only use the type described on the label. Contact the dealer if the power type cannot be identified. To operate the product using batteries or other sources of power, consult the operating manual. 10)Lightening: Unplug the power during lightening and during a long period when the product is not being used. 11) Electrical Overload: Do not plug excessive number of power cords into the outlet or extension outlet to prevent fire hazard and electrical shock. 12) Never put any object or liquid in the product. It may cause fire or electrical shock due to a potential contact with the power supply and/or short-circuit. 13) Replacement Parts: The service technician must use a replacement part with the same exact specification. Use of replacement part with incorrect specification may result in fire, electrical shock, and other safety hazards. 14) Safety Inspection: Always perform a safety inspection after a service and/or repairs. Important Safety Precaution: The product contains special components important for safety. These components are identified with in the schematic drawings. These components must be replaced with components with the exact same specification to prevent electrical shock, fire, and other hazards. Do not modify any part of the original product design without manufacturer s permission.

5-3. Operational Failure Symptoms and Actions
The PC does not recognize the DVD Writer. PC becomes slow after installing DVD Writer.
Ensure that the power cable,and S-ATA are connected properly. Use a different IDE cable connection. (Connect to the master for the secondary IDE cable if possible.) Check the status of Master/Slave pin setting.
The PC does not recognize the DVD Writer in DOS.
Install the driver again, or go to Samsung Electronics website (www.sec.co.kr) or to ODD Service website (www.samsung.ODD.com) to download and install the latest version of the driver.
The PC does not recognize the DVD Writer in Windows.
If error occurs in Windows program, then the hardware may not get recognized reinstall the program. If the drive is not recognized only in Windows, then reinstall Windows.
There is no sound from the Audio CD.
Check whether the audio cable is correctly connected to the sound output terminal on the DVD Writer and the sound card CD-IN terminal. Check that the sound card is operational.
The PC does not recognize the CD and is slow.
Check the condition of the CD, and, if necessary,use it after it has been cleaned.
The disc tray does not open.
Ensure that the power cord and cables are connected properly. If the tray does not open when the power is on, first, try to open by pressing Open/Close button again after re-booting the system. If, however, it still does not open, then turn the power off, and insert a pin or a paper clip into the emergencyhole to force the tray open.
When software MPEG player is used to playback the contents of CD, the video is jerky and slow. Disc empty message appears even with a disc in the drive.
Use a smaller playback window. Ensure the display resolution is set correctly. If not, go to the Control Panel to set the resolution to correct setting.
Accessing the drive too fast after inserting the CD in the tray may cause the PC not to recognize the CD. Open and close the tray, and then retry. Always clean the disc before use.

5-4. Compatibility Issues and Suggested Actions
What is DMA Mode?
DAM (Direct Memory Access) allows autonomous transfer of data between the main memory and peripheral devices without CPU intervention which reduces the CPU load for multi-tasking, and increases the transfer speed.
It minimizes the number of interrupts for inputs and outputs during program execution increasing system efficiency. It provides direct exchange of I/O data at high speed between the main memory and peripheral devices without going through the CPU. In DMA mode, data are transferred directly among peripheral devices without the intervention of CPU. However, DMA mode cannot be selected if the mainboard does not support the DMA mode. In addition, DMA mode cannot be selected if an external connection device is used.
-
-
In DMA mode, a number of mainboard using VIA chipsets and some specialized mainboard may have compatibility issues. Check for DMA mode support on your mainboard before using the mode. If the mainboard does not support the DMA mode, then change the mode to PIO mode.
DMA Selection
Windows98 & WinME
Select DMA by clicking Start -> Settings -> Control Panel -> System -> Hardware Wizard -> CD/ROM -> Drive Property -> Select
Windows2000 & Windows XP
Select DMA by clicking Start -> Settings -> Control Panel -> System -> Hardware -> Hardware Wizard -> IDE ATA / ATAPI Controller -> Secondary IDE Cable Controller Property -> Advanced
The DMA selection procedure may vary depending upon the OS environment. Verify that the DMA selection has been performed correctly after the selection process.
